I the implement, stubbeam and tiltable bracketFor the carrying of a ground working tool or on the lower supportingelement. implement 3|, which happens to be, in the prest For otherobjects and for more specific explaent instance, a lister plow bottom.there is a stub I nation of the invention, reference may be had to beam32 extending vertically. The working tool j the following detaileddescription taken with the 3| has an adjustable mounting bracket 33,which, accompanying drawings, in which: in turn, ispivotallyconnectedto-the lower end i a 1 Figure 1 shows a rear elevational viewof a of the stub beam 32, as at 34, and pivotally ad- I tractor with oneof its wheels in a furrow and justable forwardly thereabout by slot andbolt having the implement of the present invention means, as indicatedat 35. The working tool is a provided with trailing feet 33 forbalancing the plow in the furrow.

For attaching the stub beam 32 and plow 3| to the transverse portion ofthe lower yoke sup-- porting member 26, there is provided a bracketelement or means 31, which contains one of the principal features of thepresent invention. The bracket element has vertically and rearwardlyextending flanges 38 and 39 for attaching the same to the implement stubbeam 32. These flange members '38 and 39provide between them arearwardly extending slot 4|, in which the stub pocket 44 adapted toloosely receive the enlarged Y beam is maintained by-means of transversebolts 42, the bracket 31 being rigidly secured thereby.

In the forward face of the bracket, there is provided a transversetrough or groove 43, which is narrower in an intermediate portion 43'than at its flared end portions 43" (Figure 3). In this intermediateportion 43' there is provided a portion 29 of the transversely extendingportion of the bail supporting member 26. By having the bracket sofashioned, the stub beam with the ground working implement and bracketcan be 5 tilted within the .flared portion to the right or left on thetransversely extended portion of the supporting element 26.

The transverse portion of the supporting element 26 is maintained in thebracket trough 43 3o bylretaining plate elements 45 and 46 at each endof the trough and fixed to the bracket by means of through-bolts 45 and46' of the respective plates 45 and 46, (see Figures 3 and 4). The plateelements 45 and 46 each has forwardly extending flanged portions 45" and46", respectively, loosely connected to which, by pivot bolts 41 and 48,are pivot arm members 41' and 48', which, in turn, have fixed theretothe closed end of an inverted U-shaped member 49 by means 40 of bolts 5|and 52, respectively, the member 49 having a transverse portion 49' anddownwardly extending leg portions, Betweenthe lower ends of the legportions is a coulter wheel 53 adapted to be located forwardly of theplow bottom 3| 5 when the plow bottom is lowered into the ground for theplowing operation.

As shown in Figure 2, the coulter wheel 53 is lifted by the plow bottomwhen the plow bottom is raised to transport position on the tractor. In

50 other words, the coulter is picked up with the plow bottom and madeto pivot on the flanged portions 45" and 46" on. the bracket 31, uponraising the plow out of the ground,-the plow bottom actually carryingthe coulterwhen the -55 plow is in position of transport on the tractor.

this screw, the depth of cutting of the coulterwheel may be regulated.It will also be seen that the coulter wheel, by being attached to thebracket, will be tilted therewith and thereby maintain its verticalalignment with the implement.

It should be seen that the supporting element 26 and the bracket element31 provide two interconnected elements, one adapted to be attached tothe implement and the other to the frame structure, which are soconnected as to give a transverse tilt of one element with respect tothe other and, at the same time, a vertical rotation of one in theother. Thetwo elements thus constitute means for connecting theimplement to the frame.

0n the transverse portion of the upper supporting element 25, there isfixed by means of U-bolts 51 a quadrant 56 and the flanges of a U-shapedmember 53, which is so shaped as to include the upper end of the stubbeam 32, pro- V viding a slot in which the end of the member may movetransversely. Pivoted on the rear face of the quadrant 58, as at 66, isan adjusting lever arm 6| having a latch member 62 adapted to engagenotches 63 and 64 formed on the quadrant member 53.'-This provides meansfor adjusting the tilt of the beam 32 and its working tool 3| about thetransverse portion of the supporting member 26, the adjusting arm havingthe upper end of the stub beam 32 pivoted as at 65. By moving theadjusting arm 6| over the quadrant from the notch 63 to the notch 64,the implement is tilted from one extreme to the other. If the left wheell4 of the tractor is running in the furrow, as indicated in Figure l atA, the lever arm 6| will be moved to the notch 63, thereby straighteningthe plowbottom with respect to the ground level B. If the right wheel I3is riding in the furrow on the return trip across the field, the lever6| would be moved over to the notch 64.

For raising and lowering the implement with respect to the frame and onthe tractor, there is provided an adjusting lever 61 which is pivoted tothe pivot 21 of the flange 23 of the frame member 2| at the right sideof the tractor and which has a portion 61', the end of which is adaptedto engage a plate piece 68 on a leg portion of the upper supportingmember to lift the same.

The connection 65 serves to transmit lift to the stub beam 32. The lowersupporting element '26 will serve as guide to give parallel motion tothe vertical movement of the implement. A quadrant 69, having adownwardly extending portion 1|, is also secured to the vertical flangeportion 23 and is-adapted to cooperate with the adjusting lever 61.Movement of the adjusting lever 61 forward on its quadrant therebyraises the plow and coulter out of ground engaging position and fixesthe same to be carried by the tractor, while rearward movement of thelever 61 lowers the plow and coulter. For assisting in the lifting ofthe plow bottom out of the ground, there is provided a spring 12connected at the point 28 and to the lever 61 by means of a bracket 13thereon. Both of the levers 61 and 6| are readily reached from theoperator's station 14.

By the present invention it should now be seen that there has beenprovided a direct connected, parallel lift type of implement and anarrangement therewith for transversely tilting a plow bottom or otherground working tool with respect to the tractor; also, that there hasbeen provided an arrangement for a coulter wheel whereby the same issimultaneously lifted and lowered upon raising and lowering of theworking tool.
